#1 weed seed from bag

After conditions worsened I decided to downgrade the size of the pots and use better medium which drained better, with less clay balls in it. I also used a mixture of water, baking soda and vinegar on all my plants (not just weed, also veggies) to keep away insects and bugs, not sure if this could have caused more damge to the plants, for now plant A seems to be coming back to life. let's see if plant B and C also recover.
